The article was titled 《Synthesis, crystal structure, spectroscopic and photophysical studies of novel fluorinated quinazoline derivatives》.Quality Control of Ethyl oxalyl monochloride The article contains the following contents:
A novel small library of seven fluorinated quinazoline derivatives was synthesized and for four of them, the crystal structures were solved by single X-ray diffractometer and compared the confirmation of mols. in solution-phase using 2D NOESY experiments Taking advantage of the series prepared, the influence of various substituents on the core scaffold (fluorinated quinazoline) on its mol. conformations’ intermol. interactions and on the photoluminescent properties was described. The Hirshfeld surfaces were used to investigate the structure-directing effects of functional groups in controlling their solid-state behavior. Theor. DFT calculations were carried out for getting addnl. knowledge on crystal-state interactions as compared to a gas phase. The photo-phys. (UV and fluorescence) properties of all compounds have been studied. among the series, five compounds exhibited excellent photoluminescent properties. In the experiment, the researchers used Ethyl oxalyl monochloride(cas: 4755-77-5Quality Control of Ethyl oxalyl monochloride)
Ethyl oxalyl monochloride(cas: 4755-77-5) belongs to acyl chlorides. In the laboratory, acyl chlorides are generally prepared by treating carboxylic acids with thionyl chloride (SOCl2). The reaction is catalyzed by dimethylformamide and other additives.Quality Control of Ethyl oxalyl monochloride
